1. Exposure. Before the grain is put into storage, choose sunny days to spread 3-5 cm thick on the cement field. At noon, the grain temperature can reach 45°C, drying for more than 4 hours, turning once per hour, and killing the moths such as wheat moths and guinea pigs, as well as repelling corn elephants.
2. Low temperature insecticide. In winter or early spring, the food stalls are allowed to be frozen outdoors, and the stacking thickness is based on the temperature within the grain layer below 0°C, and freezing for more than 6 hours can kill corn elephants and corn hulls.
3. Buckwheat leaf pests. The bitter buckwheat leaves are dried to a half dry state. When storing grain, put a layer of bitter buckwheat leaves on each 15 cm thick layer of grain. To cover the seeds strictly as a standard, stack three layers. The top layer of buckwheat leaves should be thicker. Can also be the bitter buckwheat leaves, the fruit crushed by the 0.4% food weight layered in the grain heap, the last layer of appropriate sprinkle.
4. Rosin pest control. After crushed, the rosin was placed in a gauze bag, placed in a multi-point storage container, and finally sealed and sealed with a plastic film. 500 kilograms of food is divided into 3 layers of 0.5 kg of rosin.
5. Wormwood pest control. As long as the smell of wormwood can be pest control. Put a layer of dried wormwood on each 15cm grain layer and stack 3 layers. Each layer is covered with strict food. It is also possible to use insecticide-repellent Chinese herbs instead of wormwood, such as Litsea cubeba, eucalyptus leaves, pyrethrum, calamus, and the like.
6. Orange peel, red pepper, ginger pest control. The three substances can be dried and crushed, mixed in equal or unequal amounts, packaged in 50 g per bag of gauze, and 10 bags of 500 kilograms of food in 3 layers. The plastic film is sealed and stored.
7. Stem pest control. The tobacco stem contains nicotine, nicotine and other toxic substances, which can control a variety of granary pests. Stored with oysters, put chopped stalks 10 cm thick at the bottom and upper part of the pots; store them in cylinders, place chopped tobacco on the surface of the grains, seal them with plastic film after capping. New foods can be kept for 8 months without insects.
8. Torreya leaf pests. Put a fresh taro leaf in the grain tank or grain bag to prevent pests. Can also be dried and smashed citron leaves 0.5% by weight of the stored grain, mixed into the grain. Toon leaves are often replaced better.
9. Biogas pest control and extermination. Regularly passing biogas into grain or grain tanks and then sealing grain or grain tanks can prevent pests from invading and kill invading pests. In order to allow biogas to rapidly infiltrate into the grain piles, a porous bamboo can be placed around the bottom without holes and inserted into the grain heap. Then the biogas can be passed into the bamboo tubes for 10-20 minutes to kill the insects. When food is piled up in bags, it is first sealed with plastic film and the biogas is closed.
